Just back from a long weekend to the tail end of the Edinburgh Festival – lots of fringe and book festival shows packed into three days.

Best one liner from many?  By comedian Tom Wrigglesworth to a late comer clad, unlike anyone else already in the audience, in tweed jacket, slacks, polished brown shoes, white shirt and tie: Are you here to enjoy the show – or are you just doing an audit?

It was a sort of in-joke for bureaucracy aficionados matching the definition of an auditor one let me in on some time ago – An auditor is someone who watches the field of battle from the sidelines then comes on and stabs the wounded.  Remember, it was an auditor told me.

Or – more tediously but correctly – audit is a form of checking that should be minimised through better design of processes.
